is 1000w gold plus enough for my setup?

[hunkeelin]

two yes or no question

1)
Rampage v extreme
5960x
3 hdd: 1tb + 2tb + 4tb
2 ssd: 40gb + 128gb
3 case 140mm fans
h110 = 2 noctua 140mm fans
tri sli 970 gtx
I do have OC plans. I am probably pushing all 3 cards at least 1450mhz+ and my cpu at least 4.1ghz+ (i'll keep the voltage below 1.3 at all times)
Is my psu enough?

2)
Same set up except is dual sli and the third card is a zotac 970 and will be dedicated phyx. The sli gtx will be OC to 1500mhz and cpu will be oc to 4.1~4.3ghz (below 1.3v)
is my psu enough? I don't want to fry my components.

GTX 970 at stock draws around 180W in 100% gaming load, and the CPU at stock draws about 140W at 100% load. The rest of the system will take around 100W. That sums up to 780W. Suppose you want a 20% safety margin for ensuring long term reliability, you basically have peanuts left for overclocking headroom. It's far from being enough whether the third card is a PhysX card or not.

For what it's worth, I don't think using a $300+ graphics card for dedicated PhysX makes any sense at all, especially when you already have two cards that are easily fast enough on their own to handle PhysX.

I'd recommend sticking with GTX 970 SLI or upgrading the PSU. The best bang for buck on newegg at the moment is probably EVGA G2-1300 for $140 AR.

agrees with everything lehtv said

A 970 as dedicated physx card, what a waste.

EVGA G2-1300 is good price, but how's the quality?

EVGA G2-1300 is good price, but how's the quality?

It doesn't really get much better, it's a top notch unit. Review by JonnyGuru:

The Good:
beyond excellent voltage regulation
beyond excellent ripple suppression
better than 87% efficiency all the way down to the 10% load level
fully modular
extremely affordable
10 year warranty

The Bad:
nothing at all

The Mediocre:
could use a better manual
Capxon on the modular board

It might be hard to believe that such a good unit is available for such a low price, but if professional reviewers are giving it near-perfect marks, then it indeed is near-perfect. HardOCP and Techpowerup (both very stringent and thorough reviewers when it comes to PSU's) both gave it Editor's Choice awards.

I think with overclocking your prolly asking for trouble long term but it should work, you just won't have any headroom and when the caps start to degrade from age you may get issues. the 1300 EVGA G2 seems like a good idea to power your system plus it's got a 10 year warrenty. I just got a 750watt one and am pretty happy.

edit: note if you were not overclocking I don't think you would have an issue with a just 1KW PSU like you already have but the overclocking will raise the power draw on your system quite a bit and that's where it would cause issues.

 

[hunkeelin]

ok for 970 2x sli oc + 5960 oc. Will it degrade my cap in my psu?

 

[PhIlLy ChEeSe]

1000 Watt golds wear out over time with stress and the caps weaken.............They last 3 or 5 years depending on the stress and how long the system is run each turned on.

If you are just going SLI and not tri-SLI then you should be fine with your current 1KW Psu for the long haul.
